IPC: B65D5/42
Filed: 2000-09-28
Abstract: In the production radio frequency (RF) sensable objects, it is possible to produce a package, envelope, or like container which has enhanced read distance, producable by a simple method. Large areas are printed on the envelope or package in conductive ink which are separated by a non-conductive portion of the package or envelope and function as an RF antenna. Then by placing an otherwise conventional label with an RFID chip associated with it so that it bridges the conductive ink portions of the RF antenna, a much easier to sense or read product is produced. The conductive ink can be applied in a pattern, logo, and letters or character indicia. The label may have conductive pressure sensitive adhesive on one face, which actually connects the antenna sections to the RFID chip to form the operable structure that can be sensed by an RF receiver at a distance of three meters or more.

Title: System and method for establishing a diagnostic transmission mode and communcating over the same
IPC: H04M11/00
Filed: 2001-01-08
Abstract: Upon detection of a trigger, such as the exceeding of an error threshold or the direction of a user, a diagnostic link system enters a diagnostic information transmission mode. This diagnostic information transmission mode allows for two modems to exchange diagnostic and/or test information that may not otherwise be exchangeable during normal communication. The diagnostic information transmission mode is initiated by transmitting an initiate diagnostic link mode message to a receiving modem accompanied by a cyclic redundancy check (CRC). The receiving modem determines, based on the CRC, if a robust communications channel is present. If a robust communications channel is present, the two modems can initiate exchange of the diagnostic and/or test information. Otherwise, the transmission power of the transmitting modem is increased and the initiate diagnostic link mode message re-transmitted to the receiving modem until the CRC is determined to be correct.
